Abstract

This study has been carried out to analyze the research field of Gender in thyroid cancer in terms of publication output as per science citation index (1991- Mar 2010). During 1991- Mar 2010 a total of 380 papers were published by the scientists in the field of Gender in thyroid cancer. The average number of published per year 10.78%.The highest number of papers 41 were published in 2006 and 2007. There were 50 countries involved in the research in this field. USA is top producing country with 140 publications (36.84%) followed by Italy with 44 publications (11.57%),Japan with 32 publications (8.42%), Germany with 31 publications (8.15%), Sweden with 19 publications (5.00%). The most productive author is Clark OH with 11 papers dealing with thyroid cancer and 2.89% of all papers published in this research field. The most preferred journals by Thyroid topped the list with 30 (7.89%) followed by Journal of Clinical Endocrinology&Metabolism with 27 (7.10%) publications, Cancer with 22 (5.78%) publications, World Journal of Surgery with 18(4.73%) publications, Surgery with 13 publications (3.42%). NCI is top producing Institution with 15 (3.94%) publication followed by Karolinska Institute, University of California San Francisco, University of Pisa each 13 publications. Thyroid topped the list with 273 publication followed by Cancer with 131 publications, Carcinoma with 112 publications.

Abstract

Ebola virus in humans causes hemorrhagic fever with a case fatality rate of 50% to 90%. So far, there is no specific treatment or vaccine for the Ebola virus. Patients experience uncontrollable bleeding from all body orifices, with intravenous fluid replacement therapy offering little consolation. World Health Organization (WHO) declared this epidemic as an international public health emergency. Moreover, there is now considerable concern that this Ebola outbreak will threaten world security. The proliferation rate of the disease since 2013 is at an alarming rate and is simultaneously found reflected in an abnormal research literature output. A sum total of 2172 publications were captured from the PubMed covering a longer period spanned between 1985 and 2014. While tracing the development trend in both the frequency distribution of the disease and countries affected, the data of research publications in Ebola were subjected to a Scientrometric study to find out if there exists a correlation between the countries affected by a specific disease and countries contributing to Ebola research. As usual in the case of any epidemic, USA leads in Biomedical research nullifying the hypothesis of the present study while the mostly affected African countries were poor in Ebola research contributions.

Abstract

In MANET, the nodes are more vulnerable to be attacked than wired network due to its dynamic network infrastructure. These vulnerabilities are the nature of MANET structure that cannot be removed. As a result, attacks with malicious intent have been planned to exploit these vulnerabilities and disable the MANET operation by compromising the security criteria of the network can be termed as intrusion. While a system that attempts to detect such malicious action of network or compromised nodes is called Intrusion Detection System. The nodes are monitored using IDS, if any abnormal activities are occurred, and then it can able to detect different types of attack based on rule based classification. The SVM is also used to detect the attack accurately but it can be able to detect only the normal and abnormal behaviour. An Attacker can be able to affect on all the layers particularly network and MAC layer, so the attacks in the corresponding layer can be detected by using cross layer mechanism.

Abstract

Ti6Al4V owing to its high specific strength and Inconel-718 due to its high strength and oxidation resistance at elevated temperatures, have been used in Reusable Launch Vehicle-Technology Demonstrator (RLV-TD). Achieving required properties in large cross-section aerospace quality forgings of these alloys is challenging and has not been reported earlier. Hence, thermo-mechanical processing cycles have been devised to realize forgings of ~1400 mm length in these alloys and successfully used in RLV-TD. Forgings of these alloys having desired microstructures and ultrasonic quality of Class-A1 as per AMS 2630 B standard have been realized. This article discusses the processing challenges and solutions thereof.
